SPECIFICATION forming part of Letters Patent No. 442,811, dated December 16, 1890.

Application filed February 20, 1890. Serial No. 841,195. (No model.)

To all whom it may concern.-

Be it known that we, LYMAN MELVIN JONES, manufacturer, and J AMES \VEDLAKE, machinist,both of the city of Brantford,in the county of Brant, in the Province of Ontario, Canada, have jointly invented a certain new and useful Improvement in Mowers, of which the following is a specification.

The object of the invention is to improve and simplify the construction of those parts constituting the tilting and lifting mechanism of the machine and it consists in the forma; tion and arrangements of the parts hereinafter more particularly explained, and then definitely claimed.

Figure 1 is a perspective view of our improved mower. Fig. 2 is an enlarged perspective detail, partially in sect-ion, showing the connection between the coupling-bar, a sleeve, and a bracket surrounding said sleeve. Fig. 3 is a detail of the lifting-lever and 0011- nections therewith. Fig. 4 is a view showing the connection between the pitman and knife. Fig. 5 shows the socket on the knife, the cap which completes the joint between the knife and pitman, and the ball on crank of pitman.

A represents the coupling-bar pivoted on a pin a, extending from the crank-shield B, which is a portion of the main frame of the machine. The coupling bar A extends through and is loosely j ournaled in the sleeve C, within which it is held by a pin 1), fixed to and extending from the coupling-bar A. This pin 7) extends through a vertical slot made in the sleeve C, which slot permits the said sleeve to be rocked upon the bar A without permitting any .longitudinal movement thereon. Suitable arms D extend from the sleeve C and constitute the bracket on which the shoe E is hinged. F is an arm extending upwardly from the sleeve C. A rod G is connected, as indicated, at one end to the arm F and at its other end to a lever H, pivoted at d on the frame of the machine and provided with a suitable notched quadrant I for the purpose of holding the said lever at any desired angle.

It will be seen that owing to the slot in the sleeve C the shoe and cutter-bar connected with it may be by the motion of the lever H set at any desired angle. The push-bar J is pivoted at one end on the pivot (Z, and is rigidly secured at its other end to the bracket K, which has a hole in it to fit onto a convex rim e, formed on that portion of the sleeve C where the slots for the passage of the pin 1) v are made. Slots f are made through the bracket K, through which the pin 1) projects. In this way the pin 1) forms the desired connection between the bracket K and sleeve C, while permitting sufficient freedom of movement to prevent any binding of the parts when the cutter-bar is raised or lowered. The hole in the bracket K, surrounding the convex ring 6, forms a sort of ball-and-socket joint between the parts named.

L is alever pivoted on the same pin on which the shoe E is hinged. This leverL has a heel g, which extends behind the said lever and is intended to come in contact with the shoe E or other part behind the pivot of the said shoe when the said lever L is operated for the purpose of raising the cutter-bar, as hereinafter described.

M is a chain connected at one end to the lever L, and, after passing underneath the pulley N, supported by the push-bar J, is connected either directly to the lever O or by means of the rod P, as shown.

Q, is a spring connected at one end to the lever O, as indicated, and at its other end to the tongue R, he said spring being so connected that it may be adjusted with the view of increasing or decreasing its tension, as required. The said tension should be just sufficiently strong to carry the major portion of.

the weight of the cutter-bar, so that it will float over the ground without resting its whole weight thereon. oted at the point indicated, the bracket S, to which the lever T is connected, being independently pivoted on the same pivot as the said lever 0.

hen it is desired to raise the cutter-bar, the lever T is drawn back so as to bring a step 7L, formed on it, against a step j, formed on the lever 0, when by continuing the pressure the said lever O is tilted on its pivot, and owing to its connection through the chain M with the lever L the said lever is likewise acted upon until it comes in contact with the step 70. Vhen the heel of the cutter-bar is raised, the push-bar, pivoted as before speci- The lever O is loosely piv- 4 fled, permits the said elevation, as'does also the loose connection between the bracket K and sleeve 0, before described.

\Ve may mention here that as the leverO is independently pivoted the movement of the parts connected with the cutter-bar does not affect the lever T.

On reference to Figs. 4 and 5 the form of connection between the pitman and the knife will be seen. It will be noticed that the pitman X has a crank formed 011 its end, and a ball W on the end of the said crank This ball fits into a socket U, wherein it is held in position by the concave cap Y. This concave cap has a lip Z on one side to fit into a hole m, made in the heel of the knife V. A lug n is formed on the opposite side of the cap Y to correspond with a similar lug extending from the socket U. A hole is made through the two lugs, through which the bolt 0 is passed, which is the only bolt used for holding the pitman in place.

It will be seen that a concave cap made as shown may be readily detached or fixed in position by simply removing or tightening the nut on the bolt 0.

\Vhat we claim as our invention is- 1. A coupling-bar A, pivoted at one end to the frame of the machine and connected to the sleeve 0, having a convex rim e, and to which the shoe of the cutter-bar is connected, in combination with a bracket K, loosely journaled on the convex rim'ot' sleeve 0 and held by the pin 1), which passes through a slot f, made in the bracket K, as indicated, substantially as andfor the purpose specified.

2. The lever L, pivoted on the pin on which the shoe E is hinged and having a heel g eX- tendiug behind the said hinge, and a chain M or its equivalent connected to the lever L, passing round the pulley N, and connected to the pivoted lever O, in combination with the spring Q, connected to the lever O at one end and at its other end to some fixed point in the machine, and the lever T acting on said lever O, substantially as and for the purpose specified.

3. The lever L, pivoted on the pin on which the shoe E ishinged and having a heel 9 extending behind the said hingeJand a chainM or its equivalent connected to the lever L, passing round the sheave-pulley N, and connected to the pivoted lever O, in combination with a springQ and lever-bracket S, independently pivoted on the same pivot as the lever O and provided with a step 71, designed to come in contact with the step j, formed on the said lever O, substantially as and for the purpose specified.
